OpenXML Cant get namespaces to work, possible original XML file issue?

I am having trouble with importing an XML file generated by our factory machine into a SQL table. If I edit the file to remove the additional Namespaces I get the right results but as we want to automate this process that isn't feasible to do.

The start of the XML file looks like this;

<?xml version="1.0" encoding="UTF-8"?>
<LaneHistory xmlns="omlNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="omlNamespace C:\Program%20Files\Moba\Omnia%20MMI\MMI\bin\..\Application%20Data\XML\Schema\OML-LaneHistory.xsd">
<FileProperties>
    <MachineNumber>33309</MachineNumber>
    <CreationDateTime>2012-06-29T08:12:41</CreationDateTime>
    <ContentDescription>LaneHistory</ContentDescription>
    <Version>001</Version>
</FileProperties>
<Lane>
    <General>
        <StartDateTime>2012-06-29T05:50:02</StartDateTime>
        <StopDateTime>2012-06-29T06:20:07</StopDateTime>
        <LaneNumber>25</LaneNumber>
    </General>
    <Supply>
        <Property>
            <Name>Jones Heulyn Org Hse 3</Name>
            <AdditionalCode>UK20296=</AdditionalCode>
        </Property>
        <Identification>
            <TraceCode1>UK20296=</TraceCode1>
            <TraceCode2>633264</TraceCode2>

I have tried the following;

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX), @rootxmlns varchar(MAX)
SELECT @XML = XMLData FROM XMLwithOpenXML
set @rootxmlns = '<LaneHistory xmlns="omlNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="omlNamespace C:\Program%20Files\Moba\Omnia%20MMI\MMI\bin\..\Application%20Data\XML\Schema\OML-LaneHistory.xsd">/'

EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML, @rootxmlns

but get the error ;

The XML parse error 0xc00ce553 occurred on line number 0, near the XML text "". Msg 6602, Level 16, State 2, Procedure sp_xml_preparedocument, Line 1 [Batch Start Line 33] The error description is 'The following tags were not closed: LaneHistory.'.

Can anyone point me in the right direction.

Cheers jason

EXEC sp_xml_removedocument @hDoc

It looks to me like your namespace is badly formed:

set @rootxmlns = '<LaneHistory xmlns="omlNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="omlNamespace C:\Program%20Files\Moba\Omnia%20MMI\MMI\bin\..\Application%20Data\XML\Schema\OML-LaneHistory.xsd">/'

You have the "/" and ">" at the end in the wrong order. I think you just need this instead:

set @rootxmlns = '<LaneHistory xmlns="omlNamespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="omlNamespace C:\Program%20Files\Moba\Omnia%20MMI\MMI\bin\..\Application%20Data\XML\Schema\OML-LaneHistory.xsd"/>'

MSDN has an example XML namespace of:

'<ROOT xmlns:xyz="urn:MyNamespace"/>'

...for reference.

Part 2 - so your query returns nothing, I think this is because you have the attribute-centric option (1) set when you use OPENXML to query your XML. If you change this to element-centric option (2) then it should work? I did a little test with your partial XML and could pop out the Machine Number by changing the option from 1 to 2.

In very basic terms, this is attribute-centric XML:

<LaneHistory><FileProperties MachineNumber="33309"/></LaneHistory>

...and this is element-centric XML;

<LaneHistory><FileProperties><MachineNumber>33309</MachineNumber></FileProperties></LaneHistory>

So, to be clear, your OPENXML statement needs a third parameter that should be a 2.
